Data Scientist in a Data Privacy Startup (English)

Sarus Technologies is hiring!


Open Knowledge, Protect Data

Sarus software lets data scientists and business analysts work on sensitive data without accessing the data directly. They can carry on their work as usual, from database analyses to AI models with complex machine learning training, without risking any sensitive piece of information.

Sarus implements differential privacy to guarantee that analysis results do not embed personal information and that individual reidentification is impossible.
